CONVEYING MECHANISM.

Specification of Letters Patent.

Patented June 6, 1916.

Original application filed September 12, 1912, Serial No. 719,955. Divided and this application filed November 1.1, 1912. Serial No. 730,574.

To all whom it may concern:

Be it known that-I, EDWARD M, STILns, a citizen of the United States, residing at Mount Pleasant, in the county of Henry and State of Iowa, have invented certain new and useful Improvements in Conveying Mechanism, of which the following is a specification.

This application is a division of my application, Serial No. 719, 955, filed Sept. 12, 1912, and the present invention relates more specifically to improvements in conveying mechanism, particularly adapted, though not necessarily limited in its use with meat cutting mechanism, andthe primary object of the invention is to provide an improved simple, durable, and comparatively cheap conveying mechanism which will be effective and efficient in operation.

A further object is to provide an improved conveyer having means whereby the article being'conveyed will be held against distortion.

Other and further objects will appear from the following specification and appended claims in connection with the accompanying drawings; wherein this improved conveyor is illustrated in connection with a meat cutting machine and in which drawings; V V s Figure 1 is a side elevationof an improved conveyer'of this class constructed in accordance with the principles of this invention, and showing the same as applied'to a well known type of meat cutter, the latter being partly in section. Fig. 2 is a front elevation of the construction shown in Fig. 1 and is viewed from the left of Fig. 1. Fig. 3 is a top plan viewof the parts shown in Figs. 1 and 2. Fig. 4 is a detail horizontal sectional view taken on line 4'4, Fig. 2. Fig. 5 is a detail perspective view of the fly or member for transferring the slices from the re ceiver to the collector table or support. Fig. 6 is a detail sectional view on line 6-6, Fig. 4. Fig. 7 is a detail sectional view on line 77, Fig. 4. Fig. 8 is a detail sectional view on line 88, Fig. 4. Fig. 9 is a view partly in section of the fly actuating pawl.

' In the drawings there is shown a collector support adjacent the meat cutter, adapted to receive the slices of meat as they are out, and the conveyor serves in the nature of a re ce1ver for receiving each individual slice of materlal as it is cut, to convey or carry it away from the cutter. Means are also shown for transferring each slice from the receiver or conveyer to the collector support.

Referrmg now more particularly to the drawlngs, the platform of the meatholder is designated generally by the reference numoral 10 and is provided with the usual uprights 11, preferably one or both of which may be pivoted to the platform as at 12, and 1s provided with a cross bar 13, which latter may be forced down against the top of the block of meat to clamp the same firmly to the carriage. Means'arealso provided for moving the carriage backwardly and forwardly behind the cutter 14, which latter is prefer ably in the form of a disk and preferably rotates during the cutting stroke so as to bet.- ter sever the slice of meat from the piece. In the particular construction illustrated a hand wheel 15 serves as a source of power.

for imparting a relative movement to the carriage and disk. However, suchconstructions are well known 1n the art and inasmuch as they form no part of the present invention, further-specific description thereof is not necessary; j

a Each time the carriage is returned to its normal position, asshown in Figs. 2 and 3, it is advanced forwardly, a predetermined distance so that the piece of meat will protrudeout into the line of the cutting disk,

and thus insure the severing of a given stacker bears to a well known form of meat cutter. p

The meat stacker comprises a collector support 19, which is preferably arranged so as to be adjusted upwardly and downwardly, and is disposed adjacent the meat cutter.

The receiver, in the present form of this inve'ntion comprises'a carrier in the form of endless belts adapted to receive and transport the individual slices of meat as they are cut, away from the cutting disk.

The receiver or conveyer which constitutes the subject matter of this application, in the present form of the invention comprises spaced upright shafts 20, 21, arranged parallel with each other and mounted in suitable bearings in a suitably supported frame 22. The shafts 20 and 21 are arranged at an incline to the vertical, that is, they are tilted backwardly at their upper extremities toward the carriage and in a direction away from the cutterv14. The support or frame 22 for these shafts is preferably arranged to extend outwardly beyond the front face of the cutter 14 and in a direction transverse to the plane of rotation of the cutter. The receiver or earlier is preferably in the form of endless belts 23, having spaced teeth or spikes 24 projecting fro-m the cutter face thereof. Any number of these endless belts 23 may be provided and they are constructed of any suitable flexible material.

Arranged on the shaft 21 and secured thereto for rotation therewith, is-a pulley 25 which is provided'with a series of spaced peripheral grooves spaced longitudinally of the shaft and into which the belts 23 run, one gro'ove being provided for each of the belts. Mounted loosely upon the other shaft 9 20 are a series of pulleys 26 which are of a diameter less than the diameter of the pul-' ley 25' and one of these pulleys 26 is provided for each of the belts 23, as shown more clearly in Figs. 7 and 8. The pulleys 26 are spaced longitudinally of the shaft 20 and arranged intermediate each pair of pulleys 26 is a sleeve or collar 27 and these sleeves or collars are secured to the shaft 20 so as to rotate therewith in any desired or suitable manner, such as by meansof a fasteningkey or feather 28. The sleeves or collars 27 are also provided with spaced radially projecting prongs or teeth 29 and these prongs or teeth 29 are of a length slightly-greater than the prongs or teeth 24 on the belts 23, for the purposes to be hereinafter set forth. With this construction it will be manifest that when the shaft 20 is rotated the sleeves or collars 27 and the prongs or teeth 29 will be rotated therewith, while the pulleys 26 over which the belts 23' pass will have a rotary movement with respect to the shaft 20.

Motion is imparted to one of the shafts, preferably the shaft 20,- in any suitable manner from the main shaft of the machine, or the shaft to which the hand wheel 15 is connected. This is accomplished by means of a suitable shaft 30 which is geared to the main shaft 31 in any suitable manner and 'ispro vided Witha gear 32 (see Figs. -1 and 2) which latter meshes with a gear 33 on all-- Secured also to the shaft 20 for rotation therewith and preferably at the upper extremity of the shaft, is a pulley 38 over which a drive belt 39 passes and this belt 39 also passes over another pulley 40 which is secured to the shaft 21 so that the motion imparted to the shaft 20 will be conveyed to the shaft 21. shaft 20 is directly driven from the main shaft of the machine and-when rotated the shaft 20 will rotate the sleeves or collars 27 and also the pulley 38, As the pulley 38 is rotated, its motion will be imparted to the pulley 4O through-the medium of the belt 39. The pulley 40, beingsecured to the shaft 21, andthe pulley 25, being also se cured to the shaft 21, the latter will be rotatedby the shaft 21 and the rotation of this pulley 25 will impart motion to the belts 23, and as the belts are driven the pulleys 26 will rotate freely about the shaft 20. With this arrangement it will be manifest that the belts and the sleeves or collars 27 are not only rotated in the same direction, but at different rates of speed. The shaft 20 is located in close proximity to the cutter 14 and inasmuch-as the prongs 29 are of a greater length than the prongs 24, the slice just as it is cut will be picked up by the prongs 29 and will be carried around to the front of the receiver or conveyer. The shaft 20 is located in close proximity to the cutter 14, and inasmuch as the prongs 29 are of a greater length than the prongs 24, the slice just as it is cut, will be picked up by the prongs 29 and will be carried around or over the curved surface to the front of the receiver or co'nveyer, where it will be delivered to the latter.

Unless'means are provided for preventing the slice from becoming damaged, by the spreading action of the prongs on the belt with respect to each other, as they pass over the curved surface,- or around the pulleys, (and which spreading action, with respect to the slice, is compensated by the prongs on the sleeves carrying the slice around the pulleys before the prongs 011 the belt engage the slice) and further unless provisionis made for the purp'ose-of removing or detaching the slice from the prongs or teeth 29, after the slice has passed over the curved surface,

the slice would not be delivered to the conveyer 23, but would remain on the prongs 29 to be carried back and around such surface, and with the result that the slice would become-torn or cut up. In order, therefore, to obviate this objection and to prevent distortion or stretching of the slice, and at the same time remove the slice from-the prongs or teeth 29, a differential speed is given to thesleeves or collar 27, carrying the prongs It will be manifest that the I 29, and the belts 23 carrying the prongs 24. To accomplish this end, the driving mechanism and pulleys'are so arranged that the surface speed of the belts carrying the prongs 24, is slightly greater than the surface speed of the sleeves or collars 27 carrying the prongs 29. This variation or difference of speed may be of any desired extent, but in practice it has been found that good results can be obtained by permitting the belts to travel a distance of about 13 inches, while the sleeves or collars are traveling about 12 inches.

The prongs on the sleeves or collars will cause the slice to be deflected or drawn away from the prongs on the sleeves or collars. This will prevent damage to the slice by either set of prongs.

A guide 41 (see particularly Figs. 4 and 7 is provided adjacent the shaft .20, over which one'run of the'belts pass so as to permit the prongs 29 to become disengaged from the slice as the slice is carried away from the cutter by the belts and thereby prevent injury to the slice. A shield 42 is also provided adjacent the shaft 20 and at the point where the slice is severed by the cutter and beneath which the slice as it is severed passes. The receiver thus constructed and described is arranged adjacent the collector support 19 as shown more clearly in Figs. 2 and 3, and inclined away from the support, while the normal position of the collector support is in front of the receiver or carrier and just beneath the lowermost belt thereof. 7

In order to deposit the slices on the colleotor support 19 so as to stack them thereon, means must be provided for removing the slice from the belts or receiver and for disengaging them from. the prongs 24. Any suitable means may be provided for this purpose but a simple and efiicient means which has been found efficient .in

of belts as is shown more clearly in Figs.-

3, 4 and 7 and the fingers are of such a length that they will terminate short of the shaft 20 and also short of the guide 41.

When the fingers are in position between the belts, their outer faces will be below the extremities of the prongs 24 on the belts, (see particularly Fig. 6) so as to permit the slice to be carried by the receiver or carrierover the faces of the fingers. When the slices have reached the proper position on the receiver, with respect to the collector support 19, the fly is dumped or shifted so that it will remove or lift the slice from the belts and will deposit it on the ,collector support 19.

Any suitable means may dumping the fly, but. a suitable and efficient means comprises an arm 47 which is prefbe provided for erably carried by the reciprocating meat. carrier. This arm carries a dog '48 pivotally connected thereto and is controlled by the spring 49. The dog is what might be termed a one way dog, that is, when the carriage moves in one direction it will engage an arm 50 on that shaft 45 and will yield so as to pass the arm without rocking the shaft 45/ This,in the present form of the invention, occurs during the forward movement of the carriage or while the slice is being out. When the carriage returns to its normal position, thedog 48 will engage the arm 50 on the shaft 45 and rock the latter in its bearings. This will dump the fly 43 so that the slice will be removed from.

the carriage, the elastic member 51, will re-,

turn the fly to its normal position.

It is obvious that unless means'are pro vided, for adjusting the collector-support 19 as the slices are stacked thereon, a suitable distance after each slice of meat has been deposited thereon, eventually the stack of slices would become so large that the movement of the fly would be interfered with, and the slices would not be properly stacked. To overcome this difficulty, the

collector support19 is of such a construction that it may be automatically adjusted and is also preferably so arranged that this automatic adjustment will be effected by the movement of the fly, that is, each time a slice is deposited by the fly, the movement of the fly or pressure against the sup port through the slice will effect this adjustment. In order to accomplish this, the support 19 is carried by a number of uprights 53 movable in suitable guides, preferablyby passing through holes or openings in the base 54 of the machine, and nuts or collars 55 are provided on the uprights to automatically or naturally retain its adjusted position by the deposit of a slice thereon and'each time it is lowered by the action of the fly in depositing the slice. However, in order to insure that the support will maintain its lowered position, or the position to which it has been forced by the fly, retaining means are provided and preferably comprises a rack bar 57 which passes through a suitable guide or opening in the base 54 and a pawl 58 controlled by a spring 59 is also provided which cooperates with the teeth 57 so that each time the collector support is adjusted by the deposit of a slice thereon, the pawl 58 will yield and will then look the support against return movement under the stress of the springs 50. In order to permit the support to return to its normal position, a tripping means, preferably in the form of a' rock shaft 60-having a handle 61 secured thereto and located in a convenient position for the operator, is provided so that the pawl 58 may be lifted out of engagement with the teeth of the rack and when thus re leased the support 19 will be moved by the springs back to its normal position.

Obviously, the springs 56 must be of sufli cient strength to prevent the collector sup port 19 from dropping of its own weight in connection with the weight of the slices and it must also be of a strength that it will only move a distance substantially equal to the thickness of the slice being deposited thereon, while at the same time it should not be of such a strength that it would not be ad- 50 justed by the fly. It will be manifest that formly stacked and at the same time the fly with this construction the slices will be uniwill operate as a presser not only to move the collector support 19, but also to serve as a means for packing the slices as they are stacked. Obviously, the support or frame 22 may be held in position in any desired or suitable manner and braces and supports may also be provided wherever it is found necessary.

While in the present exemplification of the invention the preferred form of construction is herein shown, it is to be understood that many changes may be made in the details of construction and arrangement of the several parts, within the scope of the claims, and without departing from the spirit of the invention.

The term fly as used in the specification and claims in this case is to be considered in its broadest interpretation, that is, to mean any mechanism for lifting or dumping or even conveying the slices from the receiver or carrier and depositing them upon the collector support. Furthermore, while the entire mechanism as shown in the drawings isdescribed herein, in detail, it is to be understood that they do not all constitute a portion of the present invention, the latter being confined to the conveyer.
